INE 2024 tally sheet, type 2 scanner Oaxaca certified by comparison sample: clean control

Measured on AMD: Gemma-4-31B-IT, 136.6 s, $0.000126stored read

Option 09: row 14: the printed label read is not the one expected here: this field goes to a person, with its photo

Gemma's read breaks one of the paper's own checks, so the gate does not accept it.

Straightened by its corner marks; the right-hand column (officials' names and signatures) is blacked out before the page is stored or sent to the model.

Gemma-4-31B-IT reads the masked page on AMD; the gate checks each field as the answer arrives.

About a minute. One live read runs at a time for the whole site; yours waits in a short queue and shows its place.
